Abstract

This study investigates the use of T-shaped thermal blocks composed of fine-grained concrete and basalt slabs to enhance the energy efficiency of frame buildings. Although frame structures are widely used in modern construction for their economic and structural advantages, improving the thermal performance of their external walls remains a critical challenge. This research addresses the knowledge gap by analyzing the structural composition, thermal resistance, and condensation prevention properties of multilayer thermal blocks. A combination of experimental assessment and numerical heat transfer modeling was conducted under the climatic conditions of Samarkand using SmartCalc ThermoCalc. The results demonstrate that the use of basalt insulation and thin adhesive joints significantly reduces thermal bridges and enhances heat retention. The calculated heat transfer resistance of the wall sections exceeded the required norm (Ro ≥ 2.2 m²·°C/W), and simulations showed no condensation on the inner surface even at -15°C, ensuring indoor comfort. These findings imply that T-shaped thermal blocks are an effective, locally sourced solution for sustainable and thermally resilient construction. This has practical implications for reducing energy consumption, operational costs, and environmental impact in cold climates
